A corresponding roster move will be announced on Saturday, but it's expected to be a position player from Triple-A to help the O's as they wait to further evaluate Davis. The All-Star first baseman exited Friday's game after four innings with a left oblique injury, and the team is hopeful they got ahead of the injury.

McFarland, who was added prior to Tuesday's game in Toronto, pitched three innings in Friday's 5-0 loss to the Royals.
